PKA protected against SCA
and FIA, including SIFA

Public Key Accelerators (PKAs) are specialized hardware designed to efficiently offload the heavy computational tasks required by asymmetric cryptography algorithms. These tasks, often involving large integer arithmetic, can be computationally expensive and slow. FortifyIQ’s PKAs optimize the performance and security of public key cryptography, offering a range of solutions suited for different use cases.

Challenges in Cryptographic Security

Meeting the demands of modern cryptographic security can be challenging, especially when balancing:

  • Performance: Public key operations can impact system efficiency due to their computational complexity.
  • Compliance: Strict security standards in industries like finance, healthcare, automotive, and defense demand robust protection against advanced attacks.
  • Integration: Complex solutions can lead to higher costs and longer development cycles for SoC designs.

Fortify’s AES security evaluation by SGS

“Summary. The leakage analysis (Welch t-test) on over 30 million traces did not show statistically significant first- and second-order differences between trace sets with fixed and random inputs. The template-based DPA analysis, on the pseudo-random trace set for the profiling phase (15 million traces) and on a sub-set of 300k fix input traces for matching phase targeting the first-round S-box output, and template attack on ciphertext, did not indicate any potential information leakage.”

” The results for the soft IP presented in the report were obtained on the TOE which is the basic hardware implementation of the soft IP without additional levels of security (e.g. that are present in a secure silicon layout). Therefore the internal strength of the soft IP itself was evaluated. This indicates that the investigated features and parameters of the soft IP implementation should be robust against SCA and fault injection attacks in different implementations including ASIC. Nevertheless, according to the Common Criteria rules, the strength of the final composite product must be evaluated on its own.”
